pkgbase: Put ufs related tools and lib in their own package

It's not really useful in a jail or in a mdroot or even if a users
wants to do a full zfs machine.

Explicitly add more files to the 'runtime' package.

Change file permissions for some setuid executables so they are "o+r".
The executable itself doesn't contain any privileged information.

An example of where this is useful is when makefs(8) is creating an image
that includes /sbin/shutdown. This can now be done without root privileges.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Switch the default WARNS level for sbin/ to 6.

- Move from mount(2) to nmount(2). This should allow to convert MNT_SNAPSHOT
flag from a mount flag to FS-specific flag.
- Simplify usage. Instead of 'mksnap_ffs /mnt/foo /mnt/foo/snap' allow to
give only one argument: 'mksnap_ffs /mnt/foo/snap'. Old usage is also
accepted for now.
- Add an example of how to mount a snapshot.

- Import the HEAD csup code which is the basis for the cvsmode work.

Add the mksnap_ffs command to the sbin directory. This setuid root
program allows users in the operator group to take filesystem
snapshots. Its first use will be in support of `dump -L'.
